This node replaces the deprecated Attribute Randomize node, populating
a vector, float, integer or boolean field with random values. Vector,
float, and integer have min/max settings, which are also field aware.
The boolean type has a probability value for controlling what portion
of the output should be true. All four types have a field seed input
which is implicitly driven by the index, otherwise, all values would
be the same "random" value.
The Random Float node is now deprecated like other nodes, since it is
redundant with this node.

Flags controlling link/append code are split between two enums, one in
`DNA_space_types.h` and one in `BLO_readfile.h`.
This commit:
- Moves flags exclusively used in WM and BLO code to `eBLOLibLinkFlags`
in `BLO_readfile.h`. Flags in `eFileSel_Params_Flag` from
`DNA_space_types.h` are now only the ones effectively used by the
file browser editor code too.
- Fixes some internal utils in `readfile.c` still taking `short` flag
parameter instead of proper `int` one.
NOTE: there are a few other flags that could probably be moved to
`eBLOLibLinkFlags` (at the very least `FILE_LINK`, probably also
`FILE_AUTOSELECT` and `FILE_ACTIVE_COLLECTION`), since those are not
effectively used by the file browser, and control linking/appending
behavior, not filebrowser behavior.
However for now think it's safer to not touch that.
This commit adds to ID struct a new optional 'weak reference' to a

Draw thumbnails as strip overlay. This works for movie and image strips.
To draw thumbnails, this overlay has to be enabled and strips must be
tall enough.
The thumbnails are loaded from source file using separate thread and
stored in cache.
Drawing code uses only images stored in cache, and if any is missing,
background rendering job is started. If job can not render thumbnail,
to prevent endless loop of creating job for missing image it sets
`SEQ_FLAG_SKIP_THUMBNAILS` bit of `Sequence` flag.
To prevent visual glitches during timeline panning and zooming, `View2D`
flag `V2D_IS_NAVIGATING` is implemented. If bit is set, drawing code
will look for set of evenly distributed thumbnails that should be
guaranteed to exist and also set of previously displayed thumbnails.
Due to volatile nature of cache these thumbnails can be missing anyway,
in which case no new thumbnails will be drawn for particular strip.
Cache capacity is limited to 5000 thumbnails and performs cleanup of
non visible images when limit is reached.

This commit fully refactors the way linked IDs are made local when
appended.
Previously, `BKE_library_make_local` was (ab)used for this task, but it
was missing some contextual data and doing complex processing to try to
work around this, with limited sucess. Further more, it was nearly
impossibe to extend (e.g. to get new append behaviors necessary for the
asset project).
The new code is a dedicated append step in WM linking process.
NOTE: BPY API (`libray.load()` context manager) uses its own code here,
which still relies on `BKE_library_make_local` for appending.
Unfortunately, merging those two different code paths is not trivial so
for now this API will remain unchanged.
Fix T55629: Append already linked Data is impossible.
rBe2f99c338bd57 should have used the subversion currently defined
in Blender, instead it used one lower, so some files didn't have the
versioning applied.
Recently we have decided to avoid fancier versioning for nodes with
string inputs for attribute names when updating the attribute workflow
for 3.0. In that case we would just duplicate any node that will
have an updated version to work with fields.
We want to be able to use the "proper" ID names for the new versions
of the nodes though, so this patch adds "Legacy" to the IDs of all
nodes that will be replaced in 3.0. This commit also removes the nodes
from the add menu when the fields experimental preference is enabled,
in order to make it clear what has been updated and what hasn't.
Nodes in the "Maybe" categories in versioning_300.c can be renamed
later if necessary. For now it's probably better to be conservative,
and to keep the list complete.

Previously fluid simulation and Alembic modifiers had a dedicated function
to query the velocity for motion blur. Now use a more generic system where
those modifiers output a velocity attribute.
Advantages:
* Geometry and particle nodes can output velocity through the same mechanism,
or read the attribute coming from earlier modifiers.
* The velocity can be preserved through modifiers like subdivision surface or
auto smooth.
* USD and Alembic previously only output velocity from fluid simulation, now
they work with velocity from other sources too.
* Simplifies the code for renderers like Cycles and exporters like
Alembic and USD.
This breaks compatibility:
* External renderers and exporters accessing these velocities through the
Python API now need to use the attribute instead.
* Existing modifier node setups that create an attribute named "velocity"
will render differently with motion blur.

Previously, built-in nodes had to implement "socket templates"
(`bNodeSocketTemplate`) to tell Blender which sockets they have.
It was nice that this was declarative, but this approach was way
too rigid and was cumbersome to use in many cases.
This commit starts to move us away from this rigid structure
by letting nodes implement a function that declares the sockets
the node has. Right now this is used as a direct replacement
of the "socket template" approach to keep the refactor smaller.
It's just a bit easier to read and write.
In the future we want to support more complex features like
dynamic numbers of sockets and type inferencing. Those features
will be easier to build on this new approach.
This new approach can live side by side with `bNodeSocketTemplate`
for a while. That makes it easier to update nodes one by one.
Note: In `bNodeSocketTemplate` socket identifiers were made
unique automatically. In this new approach, one has to specify
unique identifiers manually (unless the name is unique already).

This mesh primitive enhances the Cube mesh primitive and allows the
creation of a cuboid with a configurable size and number of vertices
in all 3 directions. The Cube primitive is now similar to the Grid
primitive except that it works in 3 dimensions.
Previously it was possible to create a cube and scale it arbitrarily
along each axis. You could also subdivide the mesh, but the number of
subdivisions was equal along all axes. This meant that making the basic
frame for something like modular buildings wasn't trivial.
Inspired by tutorials and files for modular building creation.
The cuboid is created as a `Mesh` so that large meshes with millions of
faces are created quickly. Though edge calculation could be faster if
implemented here, edges are calculated using `BKE_mesh_calc_edges`
to reduce complexity, and in hopes that they may be calculated lazily
for `Mesh` in the future like vertex normals.

The storage of IDProperty UI data (min, max, default value, etc) is
quite complicated. For every property, retrieving a single one of these
values involves three string lookups. First for the "_RNA_UI" group
property, then another for a group with the property's name, then for
the data value name. Not only is this inefficient, it's hard to reason
about, unintuitive, and not at all self-explanatory.
This commit replaces that system with a UI data struct directly in the
IDProperty. If it's not used, the only cost is of a NULL pointer. Beyond
storing the description, name, and RNA subtype, derived structs are used
to store type specific UI data like min and max.
Note that this means that addons using (abusing) the `_RNA_UI` custom
property will have to be changed. A few places in the addons repository
will be changed after this commit with D9919.
**Before**
Before, first the _RNA_UI subgroup is retrieved the _RNA_UI group,
then the subgroup for the original property, then specific UI data
is accessed like any other IDProperty.
```
prop = rna_idprop_ui_prop_get(idproperties_owner, "prop_name", create=True)
prop["min"] = 1.0
```
**After**
After, the `id_properties_ui` function for RNA structs returns a python
object specifically for managing an IDProperty's UI data.
```
ui_data = idproperties_owner.id_properties_ui("prop_name")
ui_data.update(min=1.0)
```
In addition to `update`, there are now other functions:
- `as_dict`: Returns a dictionary of the property's UI data.
- `clear`: Removes the property's UI data.
- `update_from`: Copy UI data between properties,
even if they have different owners.

We now use a for_each function with callback to iterate through all sequences in the scene.
This has the benefit that we now only loop over the sequences in the scene once.
Before we would loop over them twice and allocate memory to store temporary data.
The allocation of temporary data lead to unintentional memory leaks if the code used returns to exit out of the iteration loop.
The new for_each callback method doesn't allocate any temporary data and only iterates though all sequences once.

Compressing blendfiles can help save a lot of disk space, but the slowdown
while loading and saving is a major annoyance.
Currently Blender uses Zlib (aka gzip aka Deflate) for compression, but there
are now several more modern algorithms that outperform it in every way.
In this patch, I decided for Zstandard aka Zstd for several reasons:
- It is widely supported, both in other programs and libraries as well as in
general-purpose compression utilities on Unix
- It is extremely flexible - spanning several orders of magnitude of
compression speeds depending on the level setting.
- It is pretty much on the Pareto frontier for all of its configurations
(meaning that no other algorithm is both faster and more efficient).
One downside of course is that older versions of Blender will not be able to
read these files, but one can always just re-save them without compression or
decompress the file manually with an external tool.
The implementation here saves additional metadata into the compressed file in
order to allow for efficient seeking when loading. This is standard-compliant
and will be ignored by other tools that support Zstd.
If the metadata is not present (e.g. because you manually compressed a .blend
file with another tool), Blender will fall back to sequential reading.
Saving is multithreaded to improve performance. Loading is currently not
multithreaded since it's not easy to predict the access patterns of the
loading code when seeking is supported.
In the future, we might want to look into making this more predictable or
disabling seeking for the main .blend file, which would then allow for
multiple background threads that decompress data ahead of time.
The compression level was chosen to get sizes comparable to previous versions
at much higher speeds. In the future, this could be exposed as an option.
